What determines color band 4?
Andrew Ramirez What determines color band 4?
The fourth and fifth bands are used to determine the percentage tolerance of the resistor. The fourth band (or 5th for the 5-band and 6-band) indicates the tolerance values. Here, two colors are added (gold and silver).
How do you find the value of 4 band resistors?
The fourth band (or 5th for the 5-band and 6-band) indicates the tolerance values. Here, two colors are added (gold and silver). The 6th band for a 6-band type resistor is the temperature coefficient….Resistor Band Colors.
| Color | Value |
|---|---|
| Orange | 3 |
| Yellow | 4 |
| Green | 5 |
| Blue | 6 |
How do you calculate resistor color code?
6 Band Resistor Color Code The formula for the three-band resistor color code is – 1st digit. 2nd digit. third digit x Multiplier = 1.0. 3 X100 = 10.3-kilo ohm ±5% 100 ppm/oc.
What is a 4 band resistor?
The 4-band resistor color code is the most commonly used resistor. Similar to the 3 band resistor, the first two bands always give the first 2 digits of the resistance value. The third band represents the multiplier while the fourth band represents tolerance.
How do you read the value of a resistor with color?
Decoding the nominal value of a resistor
- Decide which band is the first band.
- Look up the color of the first band in the column labeled “1st digit” and find the number associated with that color.
- Look up the color of the second band in the column labeled “2nd digit” and find the number associated with that color.
What is the purpose of the 4th band in a 4 band color coded resistor?
Resistors with high precision have an extra band to indicate a third significant digit. Therefore, the first three bands indicate the significant digits, the fourth band is the multiplication factor, and the fifth band represents the tolerance.
What are the 4 color bands for a 4700 10% ohms resistor?
The colored bands for a 4,700 ohm resistor with a ten percent tolerance are
| 1) | yellow, violet, red, gold |
|---|---|
| 2) | orange, violet, red, silver |
| 3) | yellow, violet, red, silver |
| 4) | yellow, violet, orange, gold |
| 5) | NULL |
How do you determine the color of a resistor band?
Reading and Determining the Resistor Value Hold the resistor with the gold or silver band to the right and read the color codes from the left to the right. Select the color codes from the bands on the resistor. Read the colors from left to right. The resistance value based on the color code provided is now displayed.

What is the color code for a resistor?
The standard color coding method for resistors uses a different color to represent each number 0 to 9: black, brown, red, orange, yellow, green, blue, purple, gray, white. On a 4 band resistor, the first two bands represent the significant digits. On a 5 and 6 band, the first three bands are the significant digits.
What is a resistor and the meaning of colour coding?
A resistor is an electronic component that can lower a circuit’s voltage and its flow of electrical current. In order to read the value of a resistor color code correctly, the resistor must be oriented so that the silver or gold color band is on the right. This band gives the tolerance of the resistor.
